The B+W 37mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC Nano Filter is a circular polarizing filter that reduces reflections from non-metallic surfaces such as water, glass, and glossy paint. Objects and people behind surfaces such as shop windows and car windshields become visible without image processing. B+W polarizing filters augment the purity of the intrinsic colors and increase color saturation. This filter is often regarded as the most important filter for photography.

Because the filter mounts rotate, the polarization effect can be visibly controlled in the viewfinder or on the monitor display. The B+W circular polarizer is compatible with nearly all modern cameras when beam splitters are used in the light path for TTL exposure metering or autofocus. Exposure errors are therefore avoided. The multiplying factor with HTC is 2 to 3, which is equivalent to 1 to 1.5 f-stops. Other polarizers up to approx. 3 stops. 

MRC Nano coated glass guarantees the necessary optical quality and also does not have any adverse effect on a correspondingly high-quality lens. The MRC Nano coating contains a multi-layer anti-reflective component with 7 layers per filter side to prevent annoying reflections. An outer layer with the usual dirt- and water-repellent properties is applied as the final layer. This not only provides all-around protection for the filter, but also makes it easy to clean and maintain the filter pane. The light attenuation itself is very uniform over the entire visible range and produces optimally color-neutral image results.


  • Reduces reflections from a variety of surfaces
  • Increases color saturation and contrast
  • Color-neutral to the optimum extent
  • Grease-free polarizing filter for easy rotation
  • Easier to attach due to new varnish technology
  • Durable and robust due to brass mount
  • For all lenses with front thread
  • Ideal for super wide angle to telephoto lenses
  • Made in Germany
